商业部设计院设计的带有连动小门的冷藏库门,小门开启机构中的曲柄和曲臂尺寸适用于库门开启度为180°的情况。我厂在选用时,因库门位于墙边,开启度小于180°,按图纸尺寸制造的曲柄和曲臂,安装后,发现连动小门不能全部开启,为此我们改变了曲柄和曲臂的尺寸,使连动小门达到全部开启。在库门开启度小于180°时,小门启闭机构曲柄和曲臂尺寸可以用试凑法确定,但比较麻烦,往往不能一次成功。而采用分析法尤为简
Commercial department design institute design refrigerator door with interlocking wicket. The size of crank and crank in the wicket opening mechanism is suitable for the case that the opening degree of the garage door is 180 °. I choose the factory, due to the garage door is located in the wall, opening less than 180 °, according to the size of the drawings made of crank and crank, after installation, we found that the door can not be linked together, for which we have changed the crank and crank The size of the door to move all to open. When the degree of opening of the door is less than 180 °, the size of the crank and the arm of the door opening and closing mechanism can be determined by a trial and error method, but it is troublesome and often fails to be successful. The use of analytical method is particularly simple
